Our methods can detect and classify a variety of scenebreaks, including cuts, fades, dissolves and wipes, even in sequencesinvolving significant motion.  We use a feature-based approach, and detect theappearance of intensity edges far from previous edges.  A global motioncomputation is used to handle camera or object motion.  The algorithms wepropose withstand compression artifacts such as those introduced by JPEG andMPEG, even at very high compression rates.  Experimental evidence demonstratesthat our method can detect and classify scene breaks that are difficult todetect with conventional approaches.  An initial implementation runs at about2 frames per second on a Sun workstation.<HR><P>If you wish to view the paper, you can choose from two options:<DL><!WA2><!WA2><!WA2><!WA2><A HREF="http://www.cs.cornell.edu/Info/People/rdz/MM95/mm95html.html">HTML</A><DD>The paper that will appear in the 1995 ACM Multimedia Conference.Also available in<!WA3><!WA3><!WA3><!WA3><A HREF="ftp://ftp.cs.cornell.edu/pub/dissolve/mm95.ps">postscript</A> form.</DL><DL><!WA4><!WA4><!WA4><!WA4><A HREF="http://www.cs.cornell.edu/Info/People/rdz/pamidlfinal.ps">Postscript</A><DD>The rather large (4.5 MB!) postscript paper submitted to IEEE PAMI.
